Top Fin Silenstream PF-S Refill for PF10 Power Filters 5.5in x 3.1 - (3 Count)

These work like a charm! I make sure to have them on hand because they work so well.

I really like how it fit perfectly and worked effectively.

They work just fine. Couldn’t get them locally

Very easy to change

Cheap not what I expected for the money , in store would be a better idea.

Filters come prepackaged and fit perfectly in the slot on the water filter on my sons goldfish tank. Product is exactly what it says it is, 100% recommend.

Keeps my tank very clear

I was worried that these wouldn’t be what they said. But the filter works perfectly for our tank that we bought from pet smart. Used them for a month so far no issues! Very pleased!
